You searched this because the standard answer never fully satisfied you. And it shouldn't have, because it was never the complete picture. The word "smoking" has been attached to these lines for so long that it has become a kind of shorthand that obscures what's actually happening. Smoking can affect skin in various ways, but it is not the mechanism behind these specific lines. Women who have never smoked develop them. Women who quit decades ago develop them. The actual cause has nothing to do with tobacco and everything to do with skin structure. The skin around your lips is thinner than anywhere else on your face. It has fewer oil-producing glands, which means less built-in moisture and support. And it is under constant mechanical stress, between 10,000 and 15,000 movements per day from normal talking, eating, and expression. That combination is what creates these lines. On you, and on every woman who has ever searched the same question you just searched. The reason that matters beyond just knowing the cause is what it tells you about the products you've tried. Every serum that disappointed you in this area was almost certainly developed for cheek skin. That's where skincare research and formulation is focused. Cheek skin is thicker and more oil-rich, and active ingredients are optimized and tested for that environment. The lip area is structurally different, and products built for the cheeks don't perform here the way they perform there. The mismatch is predictable once you know what you're looking at. Your past results were not a referendum on your effort or the quality of what you used. They were the outcome of using a tool designed for a different job. There's a more complete answer on the next page, and the product that follows from it.
